E1PBCIPICATION forming part of Letters Patent No. 383,191, dated May 22,1888.

(No model.)

To aZZ whom it may concern.-

Be it known that we, JOHN P. Ronna and NICHOLAS HOMER, both of Gowanda,in the county of Oattaraugus and State of New York,

have invented anew and Improved SawGumnier, of which the following isafull, clear, and exact description.

Thisinvention relates to saw-gum mers of the class illustrated,described, and claimed in Letters Patent No. 251,303, granted toPhilander Sisson on the th day of December, A. D. 1881, the object ofthe present invention being to improve the construction of the gum mcrforming the subj cot-matter of said patent.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure l is a side view of the improved form 20 of gummer. Fig. 2 is aface view thereof. Fig. 3 is asectional elevation taken on linear m ofFig. 2, and Fig. 4 is a sectional plan view taken on line y g of Fig. 3.

In the drawings, 10 represents the main body of the guminer, which iscomposed of a strip of iron, at the lower end of which there is formedan eye,1l. To theside faces ofthe lower portion of the body 10 there areriveted or otherwise rigidly connected upwardly-extending diagonalplates 12, above which plates there is secured a die-holder, 13, saiddie-holder being provided with side adjusting-screws,14, afrontadjusting-screw,15,and rear adj usting'screws,

16, which screws serve to holda die, 17, in any desired position, thedie resting directly upon the upper ends of the diagonal braces 12. In

this die 17 there is formed a V-shaped opening, 2, said openingcorresponding in form with that of the desired interdental spaces of thesaw.

Above the die 17 there are secured to the body 10 two side plates, 19,which plates extend outward beyond the forward perpendicu lar face ofthe body, and between said plates and in advance of the body there ismounted a movable bar, 20, that is rectangular in crosssection, exceptthat at a point near the lower end there is formed a die, 21, of a formcorre sponding with that of the opening 2 in the die 17. A guiding lip,22, extends downward behind the die 21, said lip entering the openingformed in the die 17. The bar 20 is normally upheld by a spring, 23,formed with an eye, 24, through which there is passed a bolt, 25, thisarrangement greatly increasing the force and elasticity of the spring.Above the bar 20 there is mounted a double-faced eccentric, 26, which ismade integral with or rigidly connected to a lever arm or handle, 27,the eccentric being pivotally supported by a bolt, 28, which extendsthrough the upper portions of the side plates, 19. In advance of the bar20 there are arranged two bolts, 29, which pass through the plates 19and serve as guides for the forward edge ofthe bar, and at the same timeall wear due to the reciprocation of the bar may be taken up bytightening the nuts of the bolts 29.

To the right-hand side of the body 10 there is adjustably connected abracket, 31, said bracket being held to the body by a set-screw, 32,which passes through a slot, 33, formed in the bracket, the arrangementbeing such that the bracket may be moved toward or from the front of thegummer. This bracket serves as asupport for the gage 34., which gage isformed with a slot, 35, through which there is passed a set-screw, 36,that engages with the bracket 31, and upon the point of the gage thereis formed a toe, 37, which enters the recesses be tween the teeth of thesaw and regulates the size and slant of such teeth as they are formed bythe gummer.

Just below the die-holder 13 the body 10 is provided with laterallyextending ears 40,that are apertured to receive retaining bolts orscrews 41, by which screws or bolts the gummer is secured to the benchor other stationary support, the arrangement being such that thesaw-body may be swung over the bench when the dies are used forshearing, a greater range of motion being thus secured than would bepossible if the gummer were supported at points above the die 17, as isthe case in the construction illustrated in the Sisson patent, abovereferred [0.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a saw-glimmer, the combination, with thesupportingframe, of the bracket 31, ad*

ICO

justabl y secured to the frame, and the gage 34, adjustably secured tothe bracket and provided with the toe 37 for engaging the recessesbetween the teeth of the saw, substantially as described.

2. In a sawgummer, the combination, with a main body,of diagonal bracessecured to the side faces thereof, a die-holder mounted above rear adjlisting-screws, a stationary die carried by the holder, a reciprocatingdie mounted above the stationary die, and a means for forcing thereciprocating die downward, substantially as described.

3. In a saw-gumnier, the combination, with a main body, of diagonal sidebraces secured E thereto, adie holder mounted above the braces i andprovided with side, front, and rear ad- I justingscrews, a die supportedby the diagoi I said braces and provided with side, front, and I nalbraces and mounted within the holder, a

reciprocating bar formed with a die and mounted between side plates thatare secured to the body of the gummer, a spring formed ertured cars 40,the upwardly-extending diagonal plates 12, a die-holder above the upper5 ends of the said plates, and side plates, 19,

i secured to bar 10 above the die-holder, sub- 5 I stantially as hereinshown. and described.
